BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front plate 2a, a side plate 3a, a bottom plate 5 and a ballast 8 which surround a lower part of a sleeper 7 in a railway.
Attach a box shape that consists of b protruding into a trumpet shape,
Press down the sleepiness of sleeper 7. Further, by attaching the flat plate 4c to the lower surface of the bottom plate 5, it is possible to prevent the plate from passing through at a right angle. The present invention relates to a tool for suppressing train vibration by inserting a rubber plate 11 between the lower surface of the sleeper 7 and the bottom plate 5 to suppress the bed mud.

[0002]

2. Description of the Related Art A train load is transmitted from a rail to a sleeper, and the sleeper body is repeatedly moved up and down and left and right, causing height, level, and deviation (hereinafter referred to as track deviation). In the existing sleeper laying place where the roadbed is weak, where the ballast can not be compacted by a large machine (before and after the railroad crossing, before and after the bridge, before and after the turnout and other electrical equipment etc.), the ballast compaction machine can only maintain for a short period of time, Track deviations are likely to occur sooner than general track locations. In particular, at the rail joint and its vicinity, the sleeper main body sank due to repeated impact loads, causing track misalignment. Also,
After a certain period of train vibration, the soil and sand rose from the roadbed and mixed with the ballast to generate bed mud, which also caused track irregularity. In addition, since the underside of the sleeper is in contact with the ballast with a surface without irregularities, the lateral movement of the train worked and caused a deviation. As a result, the ballast in the lower and side parts of the sleeper spilled out and the orbital deviation became even greater, and it was necessary to repair the orbit in a short period of time.

Due to the rolling of the rail and the like, the right angle between the sleeper and the rail was caused. This is also the underside of sleeper
This is one reason why the ballast resistance is weak because it is in contact with the ballast.

[0004]

However, if the existing sleeper is laid in a place where the roadbed is weak or where ballasts cannot be compacted by a large machine (before and after the railroad crossing, before and after the bridge, before and after the turnout, and other electrical equipment), The sleeper 7 and the rail 1 are damaged due to the track deviation due to the sinking of the sleeper 7 body subjected to repeated loading and the rail 10 moving forward.
0 right angle deviation. In addition, the track drifts due to the generation of roadbed mud due to train vibration. As a result, there was a problem of orbital repair in a short period.

[0005]

In order to solve the above problems, the present invention is a roadbed resistance enhancing tool 1 attached to the lower part of the sleeper 7. Front plate 2a. 2b, side plate 3a. Three
b, back plate 4a. A box shape consisting of 4b and the bottom plate 5 is attached. The opening 9 is directed downward in the direction of the ballast ballast 8, and the front plate 2b, the side plate 3b, and the back plate 4b project into the ballast 8 in a trumpet shape. As a result, the outflow of the ballast 8 at the lower and side portions of the sleeper 7 is suppressed and the ballast 8 is held. Each time the train load is applied to the ballast 8, the ballast 8 is tightly compacted upward in the opening 9 so that the track deviation due to the subsidence due to the train load becomes extremely small.

Further, the front plate 2b, the side plate 3b, and the back plate 4
By attaching b, the flat area of the lower part of the sleeper 7 becomes larger than the flat area of the lower surface of the sleeper 7 before, which leads to the enhancement of the roadbed resistance force.

The flat plate 4c is attached to the lower surface of the bottom plate 5 at a right angle to the longitudinal direction of the sleeper 7 so as to prevent the flat plate 4c from passing through and suppressing the right angle deviation. Further, by inserting the rubber plate 11 between the lower surface of the sleeper 7 and the bottom plate 5, the train vibration is softened and the bed mud is suppressed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The trackbed resistance enhancing tool 1 of the present invention is attached to the lower part of the sleeper 7 on the left and right ends, as shown in FIG. The mounting method is shown in Fig. 4 (the upper strip 6a and the tightening bolts 6
The ballast 8 of the ballast shoulder (ballast 8 part on the end side of the sleeper 7 in the longitudinal direction of the sleeper 7) as shown in c) is scraped out to the lower surface of the sleeper 6. With the jackpot 7 slightly lifted up by the jack, the trackbed resistance enhancing tool 1 is inserted into the gap between the underside of the pillow 7 and the ballast 8 from the X direction. After the insertion, the trackbed resistance enhancing tool 1 moves to the attachment position (the position where the front plate 2a hits the end of the sleeper 7), and then the upper strip 6a and the side strip 6b are tightened with the bolts 6c.
Fasten with and finish the installation. After fastening, the ballast 8 is compacted into a trumpet-like opening 9 by a ballast compaction machine and the jack is removed.

The back plate 4a is provided to reduce the resistance of the ballast 8 when the tool 1 for increasing roadbed resistance is inserted. The slope d of the side plate 3a is a slope because a tool of a ballast compaction machine (a tip tool for compacting the ballast 8 under the sleeper 7) can be easily inserted during compaction. The slopes c of the side plates 2b and 3b are sloped so that the side plates 2b and 3b can easily enter the ballast 8 without receiving resistance.

As a place where the roadbed resistance enhancing tool 1 is used,
Where there are many track deviations, rail joints and their vicinity,
Ballast compaction points, which cannot be done by large machines,
A considerable amount of repair work can be saved by installing it at the front and rear of the crossing bridge, other electrical equipment, or at a place where the roadbed is weak.

By mounting the flat plate 4c on the lower surface of the bottom plate 5, the ballast 8 between the flat plates 4c and 4c is tightly compacted in the opening 9 upward in the trumpet shape, so that the space between the bottom plate 5 and the ballast 8 is blocked. Also, the ballast 8 inside the opening 9 and the ballast 8 outside the opening 9 (front end of the front plate 2b, the side plate 3b, the back plate 4b) and the frictional resistance are sufficiently increased so that the ballast 8 can be passed through and the right angle can be suppressed. .

At a place where the track is often misaligned, a rail joint and its vicinity, and a place where the roadbed is weak, a rubber plate 11 is inserted between the underside of the sleeper 7 and the bottom plate 5 in FIG. Hold down the mud.

The roadbed resistance enhancing tool 1 is a steel front plate 2
a. 2b, side plate 3a. 3b, back plate 4a. 4b, the flat plate 4c, the bottom plate 5 and the side strip 6b are integrated by welding. Although the present invention has been described when the concrete sleeper 7 is used, the road bed resistance enhancing tool 1 can be attached to a wood sleeper by matching its shape.

[0014]

Since the present invention is configured as described above, the following effects can be obtained.

Since the roadbed resistance of the sleeper 7 main body is increased by attaching the roadbed resistance increasing tool 1, the sleeper 7 main body is stabilized (does not move), the occurrence of orbital deviation is suppressed, and the cycle of track repairing is suppressed. Can be extended in the long term.
